基于目标驱动的产品形态相似变换设计方法研究

目的针对目前产品设计领域中产品形态设计主要依靠设计师个人经验与灵感这一弊端,构建一种新的设计思路与方法,用于辅助设计师对产品的形态设计,使产品设计过程更加系统、科学与可视化,使产品设计结果更加美观、合理与高质量。方法以产品现有形态为基准,结合自身品牌基因与产品定位,以与目标意象相吻合的优秀产品特征要素为驱动目标,利用曲线细分算法与变形算法完成基于目标驱动的产品形态相似变换谱系,通过评价方法筛选出满意度较高的初始方案进行深化设计,最终得到与目标意象相符合且与原有产品基因相关联的设计方案。结论以汽车大灯设计为例,运用该方法完成了既保留产品品牌基因又符合产品目标意象的方案设计,验证了该方法的有效性。

Design Method of Similarity Transformation of Goal-driven Product Form

The work aims to construct new design idea and method to assist the designer in product form design, so as to make the product design process more systematic, scientific and visual, and enable the product design to be more beautiful, reasonable and of higher quality, in view of the drawback that product form design in the field of product design mainly relies on the designer''s personal experience and inspiration. Taking the existing product form as the benchmark and combined with the brand gene and product positioning, the excellent product feature elements matching the target image were selected as the driving target. Curve subdivision algorithm and deformation algorithm were applied to complete the similarity transformation pedigree of goal-driven product form. The initial scheme with higher satisfaction was screened out for an in-depth design through evaluation method. Finally, a design scheme that matched the target image and was associated with the gene of the original product was obtained. Taking automobile headlight design as an example, the proposed method is applied to complete the scheme design which not only preserves the brand gene but also conforms to the product target image, and the validity of the proposed method is verified.
